Question

Equações :
A)6X=36.
B)X-30=100.
C) 10-X=6.
D)12=2F.
E)15X=45.
F)35=X+15.

Answer 1

a) 6x = 36
     x = 36/ 6
     x = 6

b) x - 30 = 100
    x = 100 + 30
    x = 130

c) 10 - x = 6
     x = 6 - 10
     x = - 4

d) 12 = 2f
     f = 12/ 2
     f = 6

e) 15x = 45
     x = 45/ 15
     x = 3

f) 35 = x + 15
    x = 35 - 15
    x = 20

Answer 2

A= 6X=36
X=36:6
X=6

B=X-30=100
X=100+30
X=130

C=10-X=6
-x=6-10
-X=-4 (.-1)
X=4

D=12=2f
12:2=f
6=F

E=15x=45
X=45/15
X=3

F=35=x+15
35-15=x
20=X
